Claims..

Thisinvention relates-totrail'ers; and more par-A ticularly'to a' heavyduty tra-ilerl adapted for' use in suchL operations ashauling logs orthe'lik'e.

A primary object of this inventionis thepro visiorr of' an improvedheavy dutytrailer characterized-by a novelimeans forsecuringthetowingpole` thereto.l

A further object is the provision of'Y such a'- trailer havingmeanswhe'rebyl shock imparted to thewheels thereof asby' inequalities inthe road; is not traaismittedb as strainl to the towing pole.

Still another object is theY provision oi? meansl invassociationwithsuch a trailerwhereby strainon the pole as-by suddenstopping and'starting of the towingr Vehicle" is' compensated for insuch' mannerasto reduceto a' minimuml the' possibility' of breakin-gthepole thereby.

Still another object is the provision of means for securing a towingpole to such a trailer; obviatingthe-passageo bolts or other securing,means I through thetowingpole;

A still4 further object is; the provision of' such' af trailer; and'means for securing a towing pole thereto; which' will be sturdy anddurablei'n conn struction; reliable and eicient" in operation, and'relatively' simple an'd economical to'.- manufacture;

Stiil' further objects reside in the combinations of elements, features'of construction, and arrangements of parts, all as will be more fully'pointedl out" hereinafter and shown in` the` accolrrpanyingdrawings;wherein there is disclosed a preferred" embodimentV ofi this inventiveconcept;

Lilee` reference numbers refer to like parte throughout theseverallvi'ews of thedrawings.

Having: reference now to' the accompanying drawings, thereis: generallyindicated at' I-U- a supporting bunk or frame' comprised ofA a: beam*bunk' H` and a fal'se'bunk" |521, underlying" whichi are water tanks`t3' andi air' tanks W to provide pressure for the hydraulic brakes ofthetrailer; and the like. Secured; td the underside off the bunk Il)Iarey a= turntable' member IF and cppor sitely aligned tapered rollers|61 adaptedtorid'e on t-,rucltsx H, secured* to the` upper surface of-jwaterA tanks l3- to` aciiitate'l turningr or the bunk; Braces'v orsupport members F8" extendl downwardly from anges I'll on the` bottom`of' tanks I-3A being' secured'- theretoby bolts" 20, and supporti a*centrally disposed equalizer shaft 2I, the' ends` ofv shaft' t9' beingjournale'di in and secured to the supports f8; by'collars 22.

A` pair of additional axles 23" carrying a' plu'- ra'lity' of heavy'dutyn wheels' 24* at their extremities are mounted; on opposite sides ofshaft 21 andi suitably" secured asI byl bolts 2.5i' to`- opposite endsAof a pair of heavy duty leaf springs'Zl As best shown in Figure' 3',Veshaped* members 21proj'ectfrom' each" ofaxles` 2 3 inwardlytowardshaft` 211; havingv thev extremities of their legs Xedly' secured to theaxle and having' secured.

^ tothe apex of each amember 28) and 29, each' comprised*` of a1pluralityA of at' fingers: 31T pro;-

vided with' centrally disposedE apertures 31" and' adapted to' surroundshaft 21".

In the illustrative embodiment, shown meme ber 28' is provided with'three fingersl and, member 29 with two, although the' particular numberlis immaterial", and the' arrangement is such that the lingers areadapted to. interlock. theshaft 2l being passedv alternately throughV anaperture in fingers of. opposite members..

The. endsof membersz andZS are eachpro Vid'ediwith a` shank 32.threaded` atits, extremity and. adapted.. to. passthrough. al suitable.llongitudinally. extending apertureirntlie.- apereoft number 21.,l beingsecured therein. asf by nuts 3-3, and washersd..

From: the; foregoing; it. willi nowf be,y seen that any shocleimparteditofany onefof, the: wheels, 24a and, in turn, transmitted toits associated axle 23, is largely taken up by the springs 26, andrelatively minimized in its effect on the beam bunks I0 due to thepivotal relation of each of axles I9 with equalizer shaft 2l, due to theconnection above described.

Secured to the underside of frame I0 and exthereto in any desired manneras by welding or the like and provided at its extremity with anoutwardly turned leg 43. Tongues 42 are adapted to be secured to thesides of channel 35 as by brackets 44, the projecting lug 43 precludingthe complete withdrawal of the members from ltheir associated brackets.The opposite ends of members 42 are correspondingly supplied withoutwardly extending lugs 45, adjacent the point at which they aresecured to plates 4i. Lugs 45 are each provided with an aperture throughwhich extends an eye bolt 46, which are held nposition as by nuts 41. iSecured to eye bolts 46 are relatively heavy tension springs 48, theopposite ends of which are securedin suitable lugs 49 secured to airtanks I4.

The interior of each ofV plates 4| is-provided with a projection orflange 56 adapted to bite in the trailer pole 36. Plates 4I are of alength in excess oi the height of tow pole 36 and are provided at spacedpoints adjacent their upper and lower extremities with 'apertures 5l,through whichare adapted to be passed bolts 52 connecting the oppositeplate 4I and being secured in related assembly as by nuts 53.

From the foregoing it will be seen that the projecting flanges 56- ofplates 4i engaging in tow pole 36 provides .the sole fixed connectionbetween the trailer and the pole, and it will further be seen that therelatively tight engagement of the plates with the pole occasioned bytightening nuts 53 on bolts 52 will securely hold the same within tunnel35.

It`wil1V also be seen that the members 46 are, except for theirengagementv witl'rbrackets 44, unsecured to the frame, except by springs48. It will thus appear that any strain or pull exerted on the tow pole36 is resiliently absorbed by springs 48, it being pointed out that thesprings are of a sufcient strength normally to hold the tow pole 36within the tunnel 35 and effect a secure connection with the towingvehicle, but are su'iciently resilient so that upon a severe shock orAjerk imparted to the towpole, the same willbe transmitted to the trailerthrough the springs 48 in such manner as to cushion the effect of thesame. y J

From the foregoing it will now be seen that there is herein provided'aheavy duty trailer', accomplishing all the objectsof this invention andothers including many advantages ofgreat practical utility andcommercial importance.

As many embodiment'smay be made of this inventive concept, and as manymodifications may be madein the embodimentv hereinbefore shown anddescribed, it-i's to be understood that all matter herein is to beinterpreted merely as illustrative and not in a limiting manner.
